At the receiver, the CP removed data is converted back to the "frequency domain" by performing an N point DFT and is passed to the symbol Detection-Decoding block.
The recalibrated (DC component removed) data were saved for post processing and 3D visualization purposes.
While the calves were in the processing chute the accelerometers were removed, data were downloaded and accelerometers were re-initialized, and re-attached to the calves.
Notably, the removed data were considered to be compliant with anonymization requirements mandated by the US Health Insurance Portability and Accountability Act, and re-identification occurred despite this.
After patients with BMIs lower than 25 kg/m were removed, data were analysed for 91 413 patients, with mean age 56 years, including 55 094 (60%) overweight and 36 319 (40%) or obese, including 4099 (5%) with morbid obesity.
The processed, i.e. normalized, imputed, and outlier-removed data are provided as supplemental data (Data S1, S2, S3).
The ICI- and CAI-removed data are fed to the LLR computer to generate more reliable LLRs to further improve the output bit estimate.
An example of removed data can be seen in Figure 7.
Patient identifiers are removed before data are released to researchers, who use the pseudonymised HESID to identify records belonging to the same patient.
Mackey said that following concerns that the "domestic extremism" unit was holding too much data, it had been encouraged "to remove data which is either too old, inappropriate or irrelevant on a regular basis".
